Rated precision is 0.1 % relative, with a temperature drift of 0.015 %/°C, so the loop stays accurate across a panel's thermal swing. Settling time to 1 % of final value is 6 ms, fast enough for most process signals but not for high-speed control loops. Screw-type terminals accept 1 x (20...14) AWG solid wire. ## Electrical characteristics that matter The input voltage is 30 V, with a voltage drop of 4.1 V at the operating equipment. Maximum voltage ripple on the supply is 5 mV. Output can drive up to 1000 Ω load at the current output maximum — enough for a long cable run or a multi-device loop. Galvanic isolation is rated for 1500 V surge voltage, with isolation between input and output. No isolation between multiple inputs or outputs — this is a single-channel device.","metaTitle":"Siemens 3RS7020-1ET00 SIRIUS Signal Converter, 4-20 mA, 0.1%","metaDescription":"Siemens SIRIUS 3RS7020-1ET00 single-range signal converter. 4-20 mA in/out, 0.1% precision, 6.2 mm wide, snap-on DIN rail.
